Feed-forward Loop between Body Composition, Strength and Performance in Older Adults
We present evidence of a feed-forward loop relationship between certain components of the frailty syndrome: body composition, strength and physical performance level.The evidence has been found by performing statistical analysis on measures from 878 females and 588 males aged 60-97, participating in the Rancho Bernardo Study, followed for at least three visits over 12 years. In the analysis, we have used fat mass and lean mass (measured by whole body DXA scans), grip strength (measured by dynamometer) and time to get up and walk a certain distance. The results provide evidence of a feed-forward loop between these variables. The results also suggest that adverse changes in body composition would not only reduce the physical performance and grip strength, but the changes would further result in adverse changes in body composition. Our findings support the hypothesis that feed-forward loops are present between the components of the frailty syndrome at the time of development of frailty, which itself may be a manifestation of dysregulated energetics.
Despite its frequency in Mexico, research on migrant kidnapping is scant. We estimate that up to 250,000 migrants may have been kidnapped between 2006 and 2018. Even less is known about women as perpetrators in kidnapping operations. Moreover, in Mexico, r...
ConclusionCombined laparoscopic pouch resizing and distalization are safe and can lead to adequate weight loss. This technique allows the combination of an added restriction and malabsorption to the previous RYGB and could lead to an improved weight loss.
CONCLUSIONS: In this first study to address optimisation of CBCT imaging of root canal anatomy, a similar threshold dose for both scanners was identified for M1Ms with simple-moderate MB2 canal complexity. Increasing dose to enhance visualisation of more complex canal anatomy was ineffective. Selection of standard protocols (while avoiding lower kV/mA protocols) instead of high-resolution scans was a practical means of reducing patient dose. CNR is not a transferable measure of image quality. PMID: 32464075 [PubMed - as supplied by publisher]
ConclusionsPatients who receive neoadjuvant chemotherapy for liver metastasis surgery have a greater splenic volume increase, which correlates with NAFLD and a lower survival.

AbstractPurpose of ReviewGoal of this review article was to summarize and evaluate the current developments in nuclear medicine cardiovascular imaging with focus on PET/MR imaging. Furthermore, it should highlight recent topics of interest, such as sarcoidosis, inflammation, and cardiac amyloidosis for instance, which have not properly characterized with PET/MRI yet.Recent FindingsIn the last years there have been advances in experimental tracers and clinical research especially for inflammatory cardiac diseases. Most articles still focus PET/CT rather than PET/MRI, which is mostly due to a limited number of PET/MRI center...
CONCLUSION: Each drug when used as monotherapy against Leishmania spp. was effective, but the combination therapy was more effective than the individual drugs due to the additive or synergistic effects. PMID: 32463611 [PubMed - as supplied by publisher]

CONCLUSIONS: These correlates should be confirmed in other studies and, if supported, should be considered in the promotion and design of urban trails. PMID: 32464596 [PubMed - as supplied by publisher]
